Intramolecular Diels-Alder reaction of selenoaldehydes which were generated from bis(trimethylsily1) selenide and dienals gave the corresponding bicyclic adducts.
The first examples of intramolecular Diels-Alder reactions on indoles indicate that this reaction may be employed for the direct preparation of highly functionalized dihydroindoles. The hybridization of the atoms in the tether plays a crucial role.
The first examples of intramolecular cation radical Die&-Alder reactions have been established using trienes which cyclize to hydroindane systems. The extremely high endo stereoselectivity characteristic of the cation radical Diels-Alder reaction is effectively exploited to generate trans-hydroinda
